ROBERT w. L. DONLAN, 013 SEATTLE, wesiil'i feicoii.

' To all whom it may o'ncem;

Be 1" known that I, Reset W. L-. DON-1 LAN, a citizen of the U iitedfitiites, fes'i'ding' at Seattle, in the county of King and State of Washington have invented eertain new and useful lfiripfoteinn'ts iii Vhile Sprin D'fvies; of which the fol-lowing is a spear Heat-ion, v v This inventi n relates to improvements in the spring 'su-ppfts for vehicle hedies and Y the object of the'i'riventioii to provide devices of this character which, in additionto performing the usual function of Vehiel'e' sp'fing's, opeface zis' shooli=ailfisoihefs'.

The various featnif es of Iii-y invention will be illustrated and described in the accompanying dfawin'g's' and specifications.

In the drawin s, Figure 1 is a side elval- I gseeketed iii bushings 16 extendin through tion of my imphovddevices applied to a vehicle body. Fig. 2 is like View of the same With the czising' oi' i removed. Fig. 3 is a. fragmentar v'ieki siiiiilaf to Fig. 2 but with certain of its parts in difi'ereht aperihive positions. Figld is 2t transverse vei'tioalseetion through Fig. 1.

The 're'feience numeral 5' dsighsia'tes' the B0651 of a Vehicle, tindto the underside of Which is rigidly secured the casing of the improved spring sup'po'rts therefor. In pi-"msti'ice, there win be two such supports for euch axle. H

sides of the eoush Maiau of the of the saddle 'I'heihher it is provided with an oiitwardly' directed arm 11 terminating in at concave face 11; Positioned against there- 's'fieetix'we fae'es' ll of these erms' are cylin driczi'lfelenients, or rollers 12 and abcut the lzitte'r' eXtends an endless belt he chain one"suitebleflexihle bench Said belt is maintained under tension by means Of-Sljilflg: pressed rollers 14i acting against: the exterior of the belt and intermediate the rollers 12'.- F0'1" each'of the rollers 14 is pro vvidd-a post-'15 dis 'o'osecl 'a" 1ally,- or 2113- pioxim'aitely'so, tothe transverse axis of the casing, At the inner end of a post is" an enlarged head 15 which is formed with athe frame. Said' bushings "are eX'teriorly screw thiezide'd for engagementwith threads formed in the m'aertures which are prov'ided therefor the frame. Sore-W thread are also rovided Within the bushings to rl gage's'crew plugs 17 at their outer ends.

Inteip'o's'ed between each post and the assodated plug 1 is a helical spring 18.

Centrally in the easing; w lls 7 and 7 is epehing 19' of sufficient size'to permitof the movement of the axle with respect to the casing.

20 represent rectangular openings, rovided iiithe casing walls at diametrically opposite sides' of the openings 19. The purpost of the openings 20 is to accomiii 'odztte studs 21 which protrude from the opposite sides of the a'foredesofibe'd saddle members, Theopenings 20 are of greater sizes than the various studs, and are arranged to have the inner horizontal and vertical edges 20 and 20 engage theicoiresponding sides of the respective studs'when' the axle 8 is in the ielzitive'position in which it is represented in Figs. 1' 2; that is to; say, the refamed to" sides of the openings 20 will limit the centripetal movemei'its of the saddle members even when the (201181 9 is displaced from its central position. When the collar,

ing pushed downwardly by the edges 20' of,

such openings. The studs of the upper saddle members, however, are uninfluenced by the casing and these saddle members are prevented from descending by being supported on the axle collar 9, as will be understood from an inspection of Fig. 3. Consequently, the lower saddle members are separated from the upper ones resulting in the belt being spread horizontally in opposition to the power of the springs'lS at the front and back which act through the medium of the posts 15 associated therewith.

, The springs 18 at the bottom and top also resistthe ensuing downward travel of the moving saddle members and consequently all of the springs serve to withstand any change in the position 01": the casing in relation to the axle and contribute to restore the various parts to the normal positions in which they are represented in Fig.1 2.

The office of the belt 13 is to distribute the. strains among the various springs and in the accomplishment of which there will be more or less shifting movement imparted to the belt which is compensated for by the rollers 12 and 14. The springs are regulated by adjusting the bushings 16 or, if desired, the regulation may be performed through'the instrumentality of the plugs 17,

although the latter are primarily intended to afford removable closures for the bushing ends for introducing or removing the springs.

What I claim, is V 7 1. The combination of an axle, a casing. saddle members engageable with the axle and the casing, a belt inclosing the saddle members, and spring pressed devices connected to the casing and'serving to cause the belt to become operative with respect to said saddle member r 2. The combination of the casing, an axle extending therethrough, acollar provided on the axle within said casing, a plurality of saddle members, a stud on each of the saddle members, means provided in the cas-.

ing for engaging said studs, a belt surrounding said members, a plurality of posts supported by the casing, springs tending to push said posts against the belt, and means for regulating the springs, substantially as described.

3. The combination of the casing, an axle ext-ending therethrough, a collar provided for regulating the springs, substantially as.

described.

.4. In appliances of the class described, an axle provided with a collar, saddle members, a belt inclosing the saddle members, and. spring pressed devices positioned at opposite sides of the axle and acting against the belt for yieldingly holding said saddle members against said collar.

5 5. In appliances of the class described, an

, axle provided with a collar, saddle members,

a belt inclosing the saddle members, spring pressed devices positioned at opposite sides of the axle and acting against the belt for yieldingly holding. said saddle members against said collar, and means for adjusting said devices.

6. A spring support for a vehicle body comprising in combination with a casing secured to the vehicle body and an axle, a plurality of saddle members, a belt surrounding said members, a plurality of spring pressed devices acting to yieldingly retain said members in engaged position with respect to the axle, and means provided upon the respective members and cooperating with devices provided in said casing whereby said members are moved asunder when the relative positions of the body and the axle are varied in opposition to said springs and through the medium of the belt.

7. A spring support for a vehicle body comprising in combination with a casing secured to the vehicle body and an axle, a plurality of saddle members, a roller for each of said members, a belt surrounding said members and engaging the rollers, a plurality of spring pressed devices acting to yieldingly retain said members in engaged position with respect to the axle, and means provided upon the respective members and cooperating with devices provided in the casing whereby said members are moved asunder when the relative positions of the body and-the axle are varied in opposition to said springs and through the medium of the belt. 7

' 8. In apparatus of the class described, an axle, a plurality of springs arranged radially to the axle when thelatter is in its normal position, and a belt influenced by all of saidsprings whereby the axle is yieldrections radially of the axle.

9. In apparatus of the class described, an Signed at Victoria, B. 0., Canada, this axle, a casing, an endless belt surrounfliling 28th day of February, 1912. the axle and operativel connected t erewith and springs conngcted to the casing ROBERT DONLAN' 5 and acting through the medium of said belt Witnesses:
